Writing Standard form in y=mx+b
Which is the same as saying y=(slope)x+(y-intercept)
The first question I will help you solve is:
2x-3y+6=0
First you need to get "3y" by itself on one side,
to do this we must find the slope and y-intercept
Slope=-A/B
y-intercept=-C/B
So our "A" value is 2 and our "B" value is -3 and our "C" value is 6.
then we just plug in the numbers into the formula to get: -2/-3 which is 0.666666667(which is the same as 2/3) this is your slope,
and -6/-3 reduces to 2 which is your y-intercept.
Now the tricky part to put that into a y=mx+b
y=(slope)x+(y-intercept)
so you would go:
y=(2/3)x+2
So now you have that question solved. On to another.
4x-5y+2=0
so our slope equation is -4/-5
and our y-intercept equation is -2/-5
So now solve for slope(m) and y-intercept(b)
m=0.8 or 4/5
b=0.4 or 2/5
Now to plug it into our equation
y=mx+b
y=(slope)x+(y-intercept)
y=(4/5)x+0.4
For slope it is usually described as a fraction, and for y-intercept it can be described as a fraction or a decimal.
It is really easy onece you figure it out.
